-"Pet Door Replacement Collar Magnet"

I would like to create two pet doors that open by sensing magnets or radio frequencies that can be attached to their collars.

I wanted to share -- I love the pet door I ordered from Freedom Pet Pass. The door is so much better than the one I had before (2 see-thru flaps with magnets at the bottom). You advertisement is right on target - no wind or rain is coming in through your door! Thank you for such a wonderful product. I'm recommending it to several others I know who have thought about installing a dog door!

for pet doors are unique for each manufacturer. You cannot substitute one type of flap for another, therefore one cannot upgrade from one type of flap to another as each model has unique connection points, design and sometimes even method of movement. Below you will see replacement flaps and images to help determine your particular flap. Sometimes the measurements are slightly different from printed measurements, this is because some manufacturers will round-off the exact measurement. If you are uncertain or would like our opinion as to the flap you may need, please call our customer service team for assistance.

High quality pet doors are designed to seal very tightly. Some features to look for when choosing a pet door are high pile weatherstripping, numerous strong magnets and stainless steel strikes. Insects and small animals cannot push their way in through the pet door. The flaps are also sealed and do not hang open, so larger animals do not notice them. Most animals need a little conditioning to push against something that isn't already open. It's a good idea to keep all food and water away from the area near the pet door so unwanted animals are not attracted to the area. Opening and closing your "people" door many times a day to let your pet in and out wastes much more heating and cooling energy - as well as your personal energy - than a high quality pet door will. The most energy efficient pet doors have more than one flap, high pile weatherstripping and several, strong magnets that adhere to stainless steel strikes. The wall models are the most efficient because the air space between the flaps is greater than in the door models. Be sure to choose a pet door with high quality, heavy 3/16" vinyl to keep the outside air out and the inside air indoors. The 2 flaps made of 3/16" vinyl that close with alnico magnets and stainless steel strikes make Hale Pet Door the most energy efficient pet door on the market.Magnetic doors respond to the magnet in your pet’s collar key. Let your small dog outside to use the bathroom, or give your cat exclusive access to her litterbox.
